PERPETUAL CALENDAR.

SPECIFICATION forming part of Letters Patent No. 508,454, dated November14, 1893. Application filed April 3, 1893- Serial ITO-468,857. (Nomodel.)

To aZZ whom, it may concern:

Be it known that I, HoWAnD L. WEED, a citizen of the United States,residing at Spokane, in the county of Spokane and State of Washington,have invented certain new and useful Improvements in Perpetual Calendarsand I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention-relates to improvements in perpetual calendars. I

Briefly described, my improved calendar is of the ordinary hangervariety and consists of a hanger-card adapted to be hung against a wall,or, in a similar position, said card having on its face a stationaryline of lettering indicating the days of the week, a plurality of slotsor openings through which the months and years are visible, and at eachside edge a curved or rounded guide bearing for the movable date strip,ro'table disks pivoted on the rear of the card and having on theirfaces, respectively, letters indicative of the several months of ayear,a series of numerals indicating the first three figures of a numoer ofyears and a series of numerals from O to 9 indicative of the yearterminals which latter disk is positioned and arranged to rotate so astobring'the numerals thereon in line with the numerals on the othernumeraldisk, an endlessdate strip loosely mounted upon and surroundingthe lower part of said card and adapted to slide across the face andaround the side edges thereof and having on its face a series ofthirteen date-columns with dates so positioned thereon that as saidstrip is turned any seven columns will present on the face'o'f'lthecard, and in proper position relatively to the'stationary lineof week days :thereon, thirty-one day dates, and a supplerepresents afront elevation of a calendar constructed according to my invention. KFig. 2

represents a rear elevation thereof. Fig. 3

represents a plan View of the date-strip in its entire length with theedges disconnected. Fig. 4 represents a similar plan view of thesupplemental date-covering strip. Fig. 5 represents aplan view of therotatable monthand-year-indicating disks. Fig.6 represents a top edgeview of the complete calendar.

The object of my invention is to produce a calendar of the ordinaryhanger or wall variety in customary use in which the days of the weekare immovably indicated by a line of letters commencing with Sunday andterininating with Saturday and in which the dates of the respective daysof the Week for the month appear in column form below said days but, inlieu of attaching to the hanger card a series of tabs with numerals foreach month thereon, enveloping that portion of the card below the lineof day names with an endless strip of suitable flexible material havingon its face a series of thirteen columns containing date-numerals sopositioned that, as said strip is turned upon the card to bring thenumeral l under the day of the week'on whichthe first day of the monthfalls, every seven date columns so exposed at the face of the card willindicate thirty-one date numerals, and in loosely mounting upon thelower portion of said date-strip a supplemental endless strip whichenvelope and is adapt ed to slide over the lower portion of the face ofsaid date-strip and around the side edges of the hanger-card,- saidsupplementary endless strip having a series of unnumbered columns orsquares on its face registering with, but inequal in number to, thedate-squares to the date-strip thereby forming shoulders by which, assaid strips are turned, the unneces-'- sary date-terminals may becovered. a 1 represents the hanger-card which is provided with slots oropenings 2, 3, through which the names of the months and the yeardates,respectively, may be viewed tt represents a disk rotatably journaledatitherear of said card 1 and having around its ,circum. ference themonth names which register with the slot 2. 5 represents a smallerrotatable disk similarly pivoted to the card and hav- 2 ing thereon aseries of-numerals representing the first three numbers of a series ofyears" 6 represents.

which register with the slot 3.

a smaller disk 'rotatably pivoted on the said I card and having aroundits circumferencea series of numerals from 0 to 9 which, as said disk 6is rotated are, as shown in Fig. 1, brought into line with the numeralson the disk 5. By this arrangement my calendar is adapted for use for agreat many years the number depending upon the size of the disk 5. 7represents a permanent and stationary line of lettering on said cardindicating the days of a week. 8, 9, represent curved or roundedguide-bearings for the date-stri p to bepresentlydescribed.Theseguide-bearings may be formed in a variety of ways, such, forinstance, as by rearwardly-curving the side edges of the card andeither, or not, placing therein a suitable core, 10, or by attaching tothe edges of said card tubular or cylindrical strips of suitablematerial. By the use of these rounded bearings the date-strip will besmoothly guided around and have frictionless bearing upon the hangercard.

11 represents the date-strip which is formed with a series of thirteendate-columns 12 within which is arranged a series of datenumerals sodisposed that as said date-strip is turned on the hanger-card to bring aline of seven of said date-columns under the names of the days of theweek each series of said seven columns will present not less thanthirty-one day-dates.

The object of my invention being to produce a calendar which shall beperpetual in its character and yet have the general appearance of and beused in lieu of the ordinary wall or hanging calendars whose life doesnot extend beyond one year, and as the first day of the several monthsfalls upon variable days of the week it becomes necessary to duplicate aportion of the numerals on my endless and slidable date-strip. In orderto provide for the proper disposition of daydates under allcircumstances and with the least possible employment of dates the saiddates are thus arranged on the (late-strip, viz :In the top horizontalline six blank squares are left at the left hand, the numerals on thisline running from 1 to 7 inclusive; on the second line from the top thenumerals run from 2 to 14; on the third line from 9 to 21; on the fourthline from 16 to 28; on the" fifth line from 23 to'3l with four blankspaces on the right hand and on the sixth horizontal linefrom 30 to 31inclusive. Inasmuch as, in turning my date-strip around the side edgesand across the face of the date card so as to bring the date numeral 1under the name of the dayon which the particular month commences it willsometimes happen that more date-terminals are exposed to view than thereare days in the month, or a duplication of the day-dates are visible, itis necessary to provide some means whereby such redundant dates may becovered. This I accomplish in a very simple yet an entirely effectivemanner by the employment of an endless strip of suitable pliablematerial 13 which surrounds nd slides across the face of the date-strip11. This supplemental date-covering strip 13 has on its face a series ofblank columns or squares which register with the adjacent columns andsquares on the date-strip 11 but, in lieu of continuing the operativehorizontal lines of squares, 14, 15, the full length of the strip theupper line 14, consisting of but four squares terminates in an innershoulder 16, while the horizontal line of squares 15, next below theline 14 consists of but eleven squares and terminates in an innershoulder17. Itwill thus be seen that these shoulders 16, 17 areseparated from each other the distance of one square apart verticallyand seven squares apart, horizontally. These two lines 14, 15 are in thesame horizontal plane as, and, as said strip 13 is turned, travel alongand across the two lower date-lines of the date-strip. It will bereadily apparent that when the date-strip has been turned to bring theappropriate numerals under and in proper registry with'the day names byturning the supplemental strip 13 the stepped-lines 14, 15, t can bereadily brought over the redundant date-numerals on either or both ofthe lower lines on the datestrip.

18 represents knobs, buttons or equivalent devices attached in anysuitable-manner to the rear of said strips 11, 13, to facilitate themovement thereof.
